RECOIL-GUN WITH SPECIAL DEVICES FOR PROTIECTING THE SLIDE-TRACKS FROM DUST.

SPECIFICATION forming part of Letters Patent No. 756,172, dated March 29, 1904.

Original application filed .l'nly 28 1902, Serial No. 117,347. Divided and this application led December 29, 1902. Serial No. 137,011. (No model.)

To (tl/f w/wm, it ntcty/ concern:

Be it known that I, OTTO LAUBER, a subject of the Emperor of Germany, and a resident of 36% Holsterhausen-Essen-on-the-Ruhr, Germany, have invented certain new and useful Improvements in Recoil-Guns with Special Devices for Protecting the Slide-Tracks from Dust, of which the following' is a specifica-tion.

This invention relates to recoil-guns, and

Io has for its object to provide an improved means for protecting the slide-track from dust.

In recoil-guns having slide-tracks of ordinary construction there are positions in which the track is not covered by the slide-bearings, I5 and therefore not protected from dust and dirt. It follows .in consequence that in the use of the gun dust or dirt settles upon and adheres to the oily surface of the slide-track and seriously interferes with the recoil and 2o running-out movements of the gun in firing. In an application filed by me on July 28, 1902, Serial N o. 117,347, of which this is a division, I claimed, broadly, a construction by which said slide-track can be protected from dust and the like.

In the present application the improvement consists in mounting felt plates or the like in a fixed relation to the cradle.

In the drawings forming part of this specification, Figure 1 is a side elevation. Fig. 2 is a section on the line 2 2, Fig. 1. Fig. 3 is a section on the line 3 3, Fig. 2; and Fig. 4 is a section on the line 4 4, Fig. 3.

Referring more particularly to the drawings, A designates the gun-barrel, and B the cradle. The gun-barrel A is provided with guide-claws O on both sides thereof. These guide-claws O are provided with linings D, of brass or the like, and the linings are provided outside of the guide claws with heads E, which on the one hand prevent sliding of the linings and on the other hand serve for securing the sheath F, which incloses the free-lying portions ofthe slide-track of the cradle B.

Secured to the cradle by rivets H, preferably beneath tle free-lying portion of the track b, is a felt plate G, which closes up the space between the ends of the guide-claws O and the sheath'F and the cradle B.

In firing, the gun-barrel, together with its guide-claws and the sheath, recoils,whereupon the sheath and the guide-claws slide over the felt plate, preventing in all positions of the gun the entrance of dust and the like to the slide-track. 5 5

TVhile I have shown my preferred construction in the drawings attached hereto, I wish it to be understood that various changes in form, proportion, and minor details of construction may be made without departing from the spirit of my invention.

Having thus described the invention, the following is what is claimed as new therein:

In a gun with barrel-recoil, the combination of the cradle formed with a slide-track, the gun barrel mounted on said slide track through the medium of guide-claws, sheathing enveloping the edges of the slide-track, between the guide claws, and packings or plates of felt or the like, secured to the sides of the cradle, between the edges of the sheaths and the cradle, so that in recoil and runningout movements of the barrel the guide-claws and the sheaths slide over said packings or plates of felt or the like.

The foregoing specification signed at the United States consulate at Dusseldorf, Germany, this 13th day of December, 1902.

OTTO LAUBER.

In presence of PETER LIEBER, JOHANNES KRoNE.
